Description

【0001】
【発明の属する技術分野】
本発明は、熱湯または温湯を注ぐだけで緑茶の飲用を可能にする緑茶粒及びその製造方法に関する。
【0002】
【従来の技術】
日本古来の食文化の象徴と言われている緑茶は、味覚および香りにおいて優れたものがあり、その茶葉にはフラボノイドのカテキン類のほか、ビタミンE、ビタミンC、βカロチンなどの抗酸物質や有用物質が多数含まれ、保健効果が高いとされている。
【0003】
ところが、この保健効果が優れた緑茶を飲用する場合には、茶葉を受けて、温湯を注ぐことにより、茶葉のエキスの抽出を可能にする特殊なフィルタや急須などを用意する必要があり、また、抽出後の茶がらの処理が面倒であるなど、茶を飲用する前後の作業が面倒であった。また、外国旅行などの旅行や出張においては、茶葉が手荷物として嵩ばり、携帯および取り扱いに不便であるという問題があった。
【0004】
一方、これに対して携帯に便利なように、例えば、茶葉を水抽出して得たエキスと、茶葉を蒸留または溶剤抽出して得たエキスと、茶葉粉とを混合した即席タイプの粉末茶が提供されている。また、可溶性の緑茶粉末と凍結粉砕した緑茶葉粉末とを混合した即席タイプの粉末茶なども提供されている。
【0005】
【発明が解決しようとする課題】
しかしながら、このような即席タイプの粉末茶にあっては携帯や取り扱いが必ずしも容易でなく、しかも保存や飲用に際しての分量管理が難しく、適量でないと十分に良好な香りと味を楽しむことができないという不都合があった。
【0006】
本発明は前記のような課題を解決するものであり、茶葉からの水溶性物質のみでなく、脂溶性のビタミンE、βカロチン、カテキン類の抗酸化物なども同時に飲用に供することで、人体に対する十分な保健効果を得られるようにするとともに、携帯、商品管理および飲用時の分量管理を容易化できる緑茶粒及びその製造方法を提供することを目的とする。
【0007】
【課題を解決するための手段】
前記目的達成のために、請求項1の発明にかかる緑茶粒は、茎を除去した生茶葉を蒸し、揉処理および乾燥処理した茶葉を臼でひいて粒状物とし、この粒状物の焙煎を行なったものと焙煎を行なわないものを混合して錠剤形状に成形打粒してなる緑茶粒である。これにより、茶葉からの水溶性物質のみでなく、脂溶性のビタミンE、βカロチン、カテキン類の抗酸化物なども同時に飲用でき、人体に対する十分な保険効果が得られるとともに、携帯、商品管理及び引用時の分量管理を容易化できる。
【0008】
請求項2の発明にかかる緑茶粒の製造方法は、茎を除去した生茶葉を蒸し、揉処理および乾燥処理した茶葉を臼でひいて粒状物とし、この粒状物の焙煎を行ったものと焙煎を行わないものを混合し、さらに別に用意した抹茶、固化剤、茶の素および崩壊剤を加えて撹拌混合し、この混合物を錠剤形状に成形打粒したものである。これにより、カップなどに投入した緑茶粒に熱湯を注ぐだけで、簡単、迅速に緑茶本来が持つ香りおよび味を楽しむことができる。
【0009】
また、請求項3の発明にかかる緑茶粒の製造方法の実施の一形態は、前記臼でひいた茶葉を篩にかけ、篩に残った所定メッシュを超える茶葉を臼でひき直して前記その後の製造に使用することを特徴とするものである。これにより、原料の茶葉を有効利用でき、さらに茶葉を錠剤形状の成形打粒に適した粒状物とすることができる。
【0010】
また、請求項4の発明にかかる緑茶粒の製造方法の実施の一形態は、前記臼でひいた茶葉の粒状物を40メッシュ以下とすることを特徴とする。これにより、茶葉からのエキスの抽出を能率的に行うことができる。
【0011】
【発明の実施の形態】
以下、本発明の実施の形態を図について説明する。図1は本発明による緑茶粒の製造手順を示すフローチャートである。まず、一番摘みとして摘採した生茶葉を蒸気により蒸し、この生茶葉に含まれる酸化酵素を不活性化し、続いて粗揉、揉捻、中揉、精揉、乾燥といった一連の作業によって荒茶を製造する。さらに、この荒茶のうち葉の部分から茎の部分を選別、除去した後、再乾燥して、水分を例えば5%以下に仕上げる。
【0012】
続いて、この乾燥した茶葉を臼でひき、例えば40メッシュの篩にかけて粒状物(粒状化)にする。このとき、篩に残るものは繰り返し臼でひき、略全ての茶葉を粒状化する。なお、この粒状物には少量の粉状物が含まれる。このような臼による粒状化操作では、茶葉の品質を損なわずに任意の粒サイズにすることができる。
【0013】
次に、このようにして粒状化した茶葉の一部を焙煎する。この焙煎は、従来から行われている焙煎機による番茶の焙煎方法のような深煎りをせずに、例えばフライパンに粒状の茶葉を入れ、手早く強火で浅煎りする。一方、前記粒状化した残りの焙煎していない茶葉を、この浅煎りした粒状の茶葉と混ぜ合わせる。これにより焙煎していない茶葉に浅煎りした茶葉の香りが移る。
【0014】
また、このようにして得た茶葉の混合物と、色付け用として別途用意された上質の抹茶、サイクロデキストリン(包接剤)、例えばセルデックスB−100(商品名)などの固化剤、苦みを補うための無水カフェィンなどの茶の素およびカルボキシメチルカルシウムなどの崩壊剤を混ぜ合わせた混合物とを、適当な割合で再び混ぜ合わせて撹拌する。なお、このときの各材料の配合割合は、例えば、この緑茶粒10人前(10錠分)について、焙煎茶葉0.8g、緑茶葉0.7g、抹茶0.03g、固化剤1.0g、茶の素0.05g、崩壊剤0.3gとされる。
【0015】
そして、得られた混合物を、1粒が例えば重量で0.5gとなる所定サイズにて打粒する。この打粒により、錠剤形の茶が得られる。この錠剤形の茶は、通気性のない包装材に脱気封入して保存する。また、携帯や取り扱いを容易にするために、薬剤の包装で実施されているTPT包装により、例えば、2行5列で計10個ずつの包装とすれば、全体形状が極めて薄形化、小形化できるため、海外旅行や小旅行、出張などの携帯および取り扱いに極めて便利となる。なお、通常の家庭生活では、前記のように製造した緑茶粒を、例えば50〜100粒分を蓋付きびん容器などに収納して食卓などに設置しておくことにより、これを随時取り出して飲用に供することができる。
【0016】
なお、この飲用は、前記緑茶粒を湯呑に投入し、例えば70℃〜80℃の熱湯を注ぐことにより可能となる。この緑茶粒は適当な割合で混入された溶解剤により、熱湯の注入とともに速やかに溶解および拡散を始め、一部は下方へ沈澱し、このとき芳香およびエキスが拡散する。そこで、一杯目を飲用する。このとき、湯呑の底部には、沈澱した一部の緑茶粒が滞留しており、従って、一杯目の飲用後、湯呑に再び熱湯を注ぐと、前記のように溶解して湯呑の底部に残った緑茶粒は再び熱湯内で拡散し、味覚の良好な茶として2杯目を飲用することができる。このとき、最も比重の大きい緑茶粒の一部が湯呑の底に残留しており従って、今度は熱湯を注いだ上で、スプーンやマドラーなどによりその残留する緑茶粒を掻回す(撹拌する)。これにより、緑茶粒の固まりは完全に湯に溶けて拡散され、こくの味のある3杯目を飲用することができる。
【0017】
従って、このような方法により製造された緑茶粒はすべて残らず飲用可能であり、熱湯の注入により茶葉から抽出される成分のみならず、茶葉に含まれるすべての成分、例えばアミノ酸、カテキン類、ビタミン類、カフェィン類、タンニン類、その他の種々の栄養素もすべて体内に摂取可能となり、高い保健効果が得られる。
【0018】
【発明の効果】
以上のように、本発明の緑茶粒によれば茎を除去した生茶葉を蒸し、揉処理および乾燥処理した茶葉を臼でひいて粒状物とし、この粒状物の焙煎を行ったものと焙煎を行わないものを混合して錠剤形状に成形打粒してなり、得られた緑茶粒を湯呑に投入して、湯を注ぐだけで極めて簡単、迅速に香りが高く味の良好な茶を飲用できるとともに、この緑茶粒の携帯や取り扱いが容易になるため、海外や国内の旅行先や出張先でも手軽に緑茶をたしなむことができるという利点が得られる。また、茶かすが出ないため、その処理が不要になるという利点も得られる。さらに、このように茶葉を熱湯に溶解して分散し易い錠剤状とすることにより、従来の粉末茶のように熱湯の注入によってダマが生じるというようなた不都合も回避できる。また、本発明の製造方法によれば、前記緑茶粒を容易かつ有効に提供できる。

It is an object of the present invention to provide a green tea grain and a method for producing the green tea grain, which can obtain sufficient health effects on the green tea, and which can facilitate carrying, management of products, and management of a quantity for drinking.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the green tea grains according to the invention of claim 1 are obtained by steaming raw tea leaves from which stems have been removed, grinding the tea leaves having been subjected to the rubbing treatment and the drying treatment with a mortar into granules, and roasting the granules. Green tea granules formed by mixing the processed and non-roasted ones and shaping them into tablet form. As a result, not only water-soluble substances from tea leaves, but also fat-soluble vitamin E, β-carotene, antioxidants of catechins, etc. can be simultaneously consumed, and a sufficient insurance effect for the human body can be obtained, while carrying, product management and The quantity management at the time of citation can be facilitated.

Non-roasted ingredients are mixed, and matcha, a solidifying agent, a tea base, and a disintegrant prepared separately are added and stirred and mixed, and the mixture is formed into a tablet shape and granulated. This makes it possible to simply and quickly enjoy the aroma and taste inherent in green tea simply by pouring boiling water into the green tea grains put into a cup or the like.
[0009]
In one embodiment of the method for producing green tea grains according to the invention of claim 3, the tea leaves pulled by the mortar are sieved, and the tea leaves exceeding a predetermined mesh remaining on the sieve are re-pulled by the mortar. It is characterized in that it is used for: As a result, the tea leaves as a raw material can be effectively used, and the tea leaves can be made into granules suitable for tablet-shaped molding and punching.
[0010]
An embodiment of the method for producing green tea grains according to the invention of claim 4 is characterized in that the granular material of the tea leaves ground by the mortar is 40 mesh or less. Thereby, extraction of an extract from tea leaves can be performed efficiently.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a flowchart showing a procedure for producing green tea grains according to the present invention. First, the raw tea leaves picked as the first pick are steamed with steam to inactivate the oxidase contained in the raw tea leaves, followed by a series of operations such as coarse kneading, kneading, medium kneading, fine kneading, and drying to obtain rough tea. To manufacture. Further, the stem portion is selected and removed from the leaf portion of the crude tea, and is then dried again to finish the water content to, for example, 5% or less.
[0012]
Subsequently, the dried tea leaves are ground with a mortar and sieved with, for example, a 40-mesh sieve to form granules (granulation). At this time, what remains on the sieve is repeatedly ground with a mortar to granulate almost all the tea leaves. In addition, this granular material contains a small amount of powder. In such a granulation operation using a mortar, it is possible to obtain an arbitrary grain size without impairing the quality of the tea leaves.
[0013]
Next, a part of the tea leaves thus granulated is roasted. In this roasting, granular tea leaves are put into, for example, a frying pan and quickly lightly roasted with a high heat, without performing deep roasting as in a conventional roasting method of a bancha using a roaster. On the other hand, the granulated remaining unroasted tea leaves are mixed with the lightly roasted granular tea leaves. This transfers the scent of lightly roasted tea leaves to unroasted tea leaves.
[0014]
In addition, the mixture of the tea leaves thus obtained and a solidifying agent such as high-quality matcha and cyclodextrin (inclusion agent) separately prepared for coloring, such as Celldex B-100 (trade name), supplement the bitterness. A mixture of a tea base such as anhydrous caffeine and a disintegrating agent such as carboxymethyl calcium is mixed again in an appropriate ratio and stirred. The mixing ratio of each material at this time is, for example, for 10 servings of this green tea grain (for 10 tablets), 0.8 g of roasted tea leaves, 0.7 g of green tea leaves, 0.03 g of matcha tea, 1.0 g of solidifying agent, It is 0.05 g of tea base and 0.3 g of disintegrant.
[0015]
Then, the obtained mixture is pelletized in a predetermined size such that one particle becomes, for example, 0.5 g in weight. By this granulation, tea in tablet form is obtained. This tablet-shaped tea is stored in a non-breathable packaging material after being degassed and sealed. In addition, in order to make it easy to carry and handle, if TPT packaging is used to pack medicines, for example, if a total of 10 packages are arranged in 2 rows and 5 columns, the overall shape is extremely thin and small. This makes it extremely convenient for carrying and handling overseas trips, excursions, business trips, and the like. In normal household life, the green tea grains produced as described above, for example, 50 to 100 grains are stored in a bottle container with a lid or the like and set on a table or the like so that the tea can be taken out at any time and used for drinking. Can be provided to
[0016]
In addition, this drinking is possible by putting the green tea grains into a teacup and pouring hot water at 70 ° C to 80 ° C, for example. The green tea grains start dissolving and diffusing promptly with the injection of boiling water by the dissolving agent mixed in an appropriate ratio, and partially precipitate downward, and at this time, the aroma and extract are diffused. Then, drink the first glass. At this time, some of the precipitated green tea grains are staying at the bottom of the cup, and therefore, after the first drink, when boiling water is poured again into the cup, it dissolves as described above and remains at the bottom of the cup. The green tea grains are diffused again in the boiling water, and the second cup can be drunk as a good-tasting tea. At this time, some of the green tea grains having the highest specific gravity remain at the bottom of the teacup. Therefore, after pouring hot water, the remaining green tea grains are stirred (stirred) with a spoon or a mudler. As a result, the mass of the green tea grains is completely dissolved and diffused in hot water, and the third cup with body taste can be drunk.
[0017]
Therefore, all the green tea grains produced by such a method are drinkable, and not only the components extracted from the tea leaves by the injection of boiling water, but also all the components contained in the tea leaves, for example, amino acids, catechins, vitamins , Caffeine, tannins and other various nutrients can all be taken into the body, and a high health effect can be obtained.
[0018]
【The invention's effect】
As described above, according to the green tea granules of the present invention, the raw tea leaves from which the stem has been removed are steamed, and the tea leaves that have been rubbed and dried are ground with a mortar to obtain granules. A mixture of non-infusions is formed into a tablet shape and granulated, and the resulting green tea granules are poured into a teacup and poured into hot water. Since the green tea grains can be drunk and easily carried and handled, there is an advantage that the green tea can be easily prepared at overseas and domestic travel destinations and business trip destinations. In addition, there is also an advantage that the processing is not required because no browning is produced. Further, by dissolving the tea leaves in hot water to form a tablet that is easy to disperse, it is possible to avoid such inconveniences as in the case of conventional powdered tea, such as the formation of lumps due to the injection of hot water. Further, according to the production method of the present invention, the green tea grains can be provided easily and effectively.
